Cultural relics from the late Neolithic period (about 3,000 to 4,000 years ago) and the Southern Song Dynasty have been discovered in Ma'anshan. In the 1910s, the area was still a small village, and the villagers were engaged in traditional rural economic activities such as agriculture and fishing. From the 1950s to the 1970s, Japanese companies came here to mine magnetite. The iron ore reserves in Ma’anshan were estimated to exceed 7 million tons. However, during the oil crisis in the 1970s, the cost of mining increased significantly, and the Hong Kong government decided to develop Ma On Shan into a new town, so the mine was closed in 1976.
The development of the new town of Ma On Shan began in 1980. After decades of continuous development, Ma On Shan has become a new town with many housing estates and shopping malls. The Ma On Shan Country Park was delineated on April 27, 1979, covering an area of 2,880 hectares, so that the green belt of Ma On Shan can be protected during the urbanization period.
